Question

I really don't know where to go with this. I just need help with it fast. because idk what I'm doing I'm giving max points.

Answer 1

This is what i would put Because they have given you slope and y intercept .

Equation of line format

Y=mx+b

Where slope is "m" : -1/2

Where Y-intercept is "b": 12

Therefore,

Y= -1/2x+12

Answer 2

y=ax+b
a... slope
b... interception on the line y

you get the equation y=-1/2 *x + 12
